Title:
IMAGE PROCESSOR
Document Type and Number:
Japanese Patent JP3178482
Kind Code:
B2
Abstract:
PURPOSE: To transmit the aspect ratio of an image signal, composed selectively of plural image signal, to video equipment as a trailing stage.
CONSTITUTION: ID Deciding circuits 22 and 24 decides ID signals indicating the aspect ratios of image signals inputted to input terminals 10 and 12 and output the decision results to an ID processing circuit 32. The 10 processing circuit 32 makes a converting and selective composing circuit 26 converts an image signal, which has an aspect ratio different from a set aspect ratio to the set aspect ratio according to the aspect ratio setting signal from an input terminal 14 and the decision results of the ID deciding circuits 22 and 24. The circuit 26 performs selection and composition after the conversion. An ID adding circuit 28 outputs the output image signal of the circuit 26 after adding the ID signal indicating the aspect ratio or without adding the ID signal according to the ID addition/nonaddition control signal from an input terminal 16.
